Biomass Pellets Manufacturing for Fuel to Energy
Nowadays the biomass pellet manufacturing industry booms, so unavoidably there are sellers who sell bad quality pellets at best quality prices, which greatly harms customer’s interests. However, for most pellet users, they only keep in mind that the higher price it is, the better quality pellets have.
The raw material for biomass pellets making varies from wood sawdust, stalk, peanut shell, cotton stalk, corn stalk and straw, to household garbage. While wood pellets have the highest combustion value, then are stalk pellets, and household garbage pellets are the worst.
Over 40% of electricity worldwide is generated by coal-fired power plants. Coal has the largest carbon dioxide emissions per unit energy of all fossil fuels, and coal-fired power plants are a major source of man-made carbon dioxide emissions. Coal-fired power plants generally have a life of 20 to 50 years and represent a huge global capital investment. It is not economically feasible to retire these coal-fired power plants and replace them with greener technology. It is possible, however, to reduce their carbon dioxide emissions by replacing some of the coal with biomass - burning both fuels together which is called co-firing.

Overview
Biomass is inherently bulky and difficult to transport and store -- think of a bale of hay. Shipping bales of hay from a plantation in Asia or Africa to a customer in Europe or the US is not practical. The volume of the biomass must be reduced in a process called densification, and pellets are a good example. A pellet is simply biomass that is dried, made into a powder and pressed under high pressure into a pellet that is about the thickness of a pencil and 1 inch long. For large-scale applications, pellets are shipped in bulk in the hold of a ship, and handling is similar to the handling of bulk rice or grain.
Properties of Biomass Pellets
Properties of Biomass Pellets
Biomass pellets are generally a better-performing fuel, compared to their raw feedstock. The pellets are more energy dense and easier to transport and feed into automated feed systems. These advantages, when combined with the renewable and environmentally sound properties of the feedstock, make biomass pellets a viable source of green energy.
A wide array of biomass materials can be used to manufacture pellets. Most pellets today are made from sawdust and other wood waste. The demand for pellets has exceeded the amount of wood and agricultural waste available, and dedicated energy crops such as Giant King Grass, switchgrass, and miscanthus are strong alternatives. Pellet mills are commercial enterprises, and equipment for making pellets is available from many sources.
A biomass briquette is similar to a pellet but is larger-- up to 3 1/2 inches in diameter and 1 foot long. Briquettes are often used in industrial applications that generate heat or steam rather than electricity.
In addition to electricity generation, there is also a market for biomass pellets for residential heating and cooking.
